Kessler, a former Washington Post reporter who said he has known Donald and Melania Trump for two decades, will hold a book signing for his new book, The Trump White House: Changing the Rules of the Game, from 3:30 to 5 p.m. Saturday at the Palm Beach Book Store, 215 Royal Poinciana Way.

The book signing comes just days after FBI agents raided the office and hotel of Trump’s lawyer, Michael D. Cohen. According to the New York Times, agents were looking for details and documents about whether Cohen violated campaign finance laws to cover up negative details about Trump during the 2016 election.

Kessler’s book, however, focuses on much of the positive from Trump’s time in the White House. In the book, Kessler said he does not shy away from praising Trump and what Kessler called his "magnificent record" of achievement during his first year as president. Kessler said he wrote the book to refute the "myths" about Trump that he sees in the media.

"I wanted to tell a truthful story," Kessler said.

One of the book’s 25 chapters is devoted to Trump’s time in Palm Beach, where Kessler said he details Trump’s New Year’s Eve parties at Mar-a-Lago and the club’s push to openly accept minorities as members. Kessler said Trump liked defying the rigid, unspoken principles that kept some Palm Beach clubs from allowing in Jews or African Americans.

"I wanna be loved," Kessler said Trump told him, "and I enjoyed sticking it to the old guard."

Kessler said there are two sides to Trump: the side that is often portrayed on television, the side that makes "outrageous comments"; and the thoughtful, compassionate, deliberate side.

"That’s the one the real insiders know," Kessler said, "and who I know."

Kessler brushes off the personal attacks Trump often makes through Twitter — such as criticizing Amazon, condemning the FBI and even insulting actor Alec Baldwin — as inconsequential. Kessler points to what he said are Trump’s irrefutable successes in helping the economy, lowering the unemployment rate and "getting rid of ISIS."

Eventually, Kessler said, Trump will be remembered as one of the "greatest presidents."

"You can put the blinders on and focus on the comments that disturb everybody," Kessler said. "(But) years from now, people will remember the results, which are very obvious. And they’re going to forget about the tweets and the controversies."
